Is there another universe in a black hole?
It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe. There’s no reason to think our universe is any different.
Why do voids exist?
Voids are believed to have been formed by baryon acoustic oscillations in the Big Bang, collapses of mass followed by implosions of the compressed baryonic matter. Starting from initially small anisotropies from quantum fluctuations in the early universe, the anisotropies grew larger in scale over time.
Is there a multiverse out there?
The Universe is out there, waiting for you to discover it. ever-expanding cosmic ocean, is one depiction of the Multiverse idea. The idea that two of these bubble Universes could have collided or otherwise interacted is disfavored by both theory and observation. No matter how far we look out in the Universe, there’s always more “Universe” to see.
Can two universes collide?
In such a bubbling multiverse of universes, it seems inevitable that universes would sometimes collide. But for decades cosmologists neglected this possibility, reckoning that the odds were small and that if it happened, the results would be irrelevant because anyone and anything near the collision would be annihilated.
Did the universe ever suffer a collision?
There are tantalizing hints that our universe has already survived such a collision—and bears the scars to prove it. Aguirre has organized a conference on Grand Cayman to address just such mind-boggling matters. The conversations here venture into multiverse mishaps and other matters of cosmological genesis and destruction.
Is the universe just one of many universes?
Aguirre is one of a growing cadre of cosmologists who theorize that our universe is just one of many in a “multiverse” of universes. In their effort to grasp the implications of this idea, they have been calculating the odds that universes could interact with their neighbors or even smash into each other.
